if omit semicolon, code doesn't compile. def checkradiobutton(xml: dslbuilder): string => xmltree = { val inputs = top(xml).\\*(haslocalnamex("input")); { (buttonvalue: string) => // code omitted } } my guess that, without semicolon, scalac thinks partial function argument \\* method, instead of return value. (it isn't partial function, way, it's total function.) can without semicolon here? i've never had use semicolon @ end of line before in scala. i’d write instead: def checkradiobutton(xml: dslbuilder): string => xmltree = { val inputs = top(xml).\\*(haslocalnamex("input")); (buttonvalue: string) => { // <-- changed position of { // code omitted } }

this question related enter link description here . have histogram see difficult compare bares. there method better represent information better comparison eyes?thanks. perhaps want logarithmic y/x-axis. possible using workaround, explained here: why histogram become incorrect when change y-axis scaling 'log'? cannot use 'yscale','log' , because: the bars incorrectly displayed; histogram bars either become lines or disappear entirely.

i have interface written in c# , implemented classes. possible can add 1 more property optional in interface , without modifying exiting implemented classes? e.g public interface ishape { int area { get; } } public class findwindow : ishape { public int area { { return 10; } } } in findwindow written. possible can add 1 optional property , not implementing in existing class. ie, public interface ishape { int area { get; } //optional //string windowname{get;} } public class findwindow : ishape { public int area { { return 10; } } //windowname not implementing here } public class findwindowname : ishape { public int area { { return 20; } } public string windowname { { return "stack overflow"; } } } there's no concept of optional members of interface. what need here define 2 interfaces. 1 con

i'm using google closure's xhrio facilities send post request url. when response request 302 redirect, i'd redirect user's browser url being redirected to. i've tried calling getlasturi on object passed callback, returns uri of request, rather of subsequent redirection. getstatus returns 200. know request being redirected, because can see in chrome's network request viewer. the temporary redirect (302) handled browser, , javascript never gets see it. we had similar problem, , solved modifying server side code send 401 instead of 302 on encountering header (x-http-method-override) have explicitly set in request. server response can include redirection url in response (along 401 status). this stackoverflow question illustrates server side changes: " cannot handle 302 redirect in ajax , why?

i stuck @ correctly disposing threads, created rx, on application exiting. see in process explorer after application closed, threads still running, causing io exceptions. class program { static void main(string[] args) { compositedisposable subsriptions = new compositedisposable(); subscriptions.add(observable.interval(timespan.fromseconds(15)) .subscribe(_ => { getdata(); })); thread.sleep(timespan.fromseconds(20)); subscriptions.dispose(); } } } if see if uncomment subscription.dispose(), thread terminates without getting data. appreciated. thanks you need sort of delay between subsriptions.add(...) , subscriptions.dispose() . without delay between there, app subscribing , disposing them immediately, no time threads work. (and thread.sleep(1000) doesn't work, since inside subscription function, not part of main function.)

what trying added 2 buttons disabled default.when add item buttons enable once click receipt button checkbox checked should go away working in laptop not in fiddle , if click receipt should removeattr checked check box , buttons should disable because no checkbox checked..here code jsfiddle javascript: // json data object var data = json.parse('{ "122233334444": ["book","three musketters","de7598490587","7584092043857", "03/18/13 11:17:51 am","03/18/13 11:17:51 am", "1" ], "122223355552":["ebook","fall colors","xyz29494949","7584092043857", "03/18/13 11:17:51 am","03/18/13 11:17:51 am", "2" ], "122223355533":["ebook","snowfall","xyz29494949","7584092043857", "03/18/13 11:17:51 am","03/18/13 11:17:51 am", "3" ] }'); $("#submitid&q

in below code 'console.log('this not print!')' statement not execute. should execute according facebookstrategy. passport.use( new facebookstrategy({clientid: facebook_app_id, clientsecret: facebook_app_secret, callbackurl: "/home"}, function(identifier, profile, done) { process.nexttick(function () { console.log(' not print!'); return done(null, profile); } );})); basically, authentication thru passport-facebook takes place not able recover profile data. app.get('/home', function(req, res){ console.log(req.user); res.render('home', {user: req.user}); }); the above prints 'undefined' means above app.get(...) did not receive facebook profile data. what doing wrong? there anyway save (get) facebook profile data after authentication? above callbackurl: "/home" is wrongly declared. should be: callbackurl: "/auth/facebook/callback" for more on discussion https://github

is possible following signed out user without triggering .consumer being called on nil error? if signed_in? && current_user.consumer puts "hello world" end for of site have had nest these types of conditionals like: if signed_in? if current_user.consumer end end ...which doesn't bad, when have lots of other code on page, can hassle.. i want statement signed_in? evaluated , if true second conditional evaluated... in single line. possible? yes! ruby supports short-circuiting logic, first code block want: if signed_in? evaluates false , ruby interpreter lazy , not bother evaluating rest of condition. similarly, if user not signed in, !signed_in? || current_user.banned? short-circuit when realizes !signed_in? true , not bother evaluate current_user.banned? .

i have function call starts 10 threads. before start of these threads , have from collections import defaultdict output = defaultdict(dict) and output empty. each thread generate data write dictionary. something like: output['water'] = 'h20' output['fire'] = 'delta of oxygen' .... the threads add items , not iterate on of other items or modify other items. output['water'] being item different output['fire'] . can guarantee no 2 threads going create same item. is, each thread t has unique i. in code: output[i] unique per thread. is dictionary thread safe in regard? yes. if using cpython , strings keys, yes. gil in cpython ensures 1 thread executes bytecode @ time, , setting key value in dict happens in single opcode, store_subscr . if not using cpython, or using key has custom __hash__ , __eq__ , or __cmp__ methods, bets off. if had soapbox, i'd hop on , warn of evils of relying on implementation deta
